Abstract

The invention provides for a wiper arm for a windshield wiper system comprising a fixing element (12) for connection to a drive shaft, whereby a tiltably-fixed cover unit (24) is provided for at least partially releasing the fixing element (12). It is proposed that the cover unit (24) can be engaged with the fixing element (12) in the tilted position. A cover unit for a wiper arm is also proposed.

Claims

1. Wiper arm (10) for a window wiper system, with a fastening part (12) for connection to a drive shaft, wherein a tiltably fastened cover unit (24) having a top side (40) and two side wings (26, 28) which are open to a front side (34) and are connected via a closed rear side (36) is provided for at least partially releasing the fastening part (12), and the cover unit (24) can be latched in the tilted state to the fastening part (12), characterized in that, on an inner side of at least one side wing (26, 28), the cover unit (24) has an inwardly projecting rib (30, 32) elongated in a direction generally aligned with the top side for latching of the cover unit (24) in the tilted state, the rib (30, 32) being spaced from a rotary support (52, 54) of the cover unit (24) and where it is further located between the rotary support (52, 54) and the top side (40) and, upon tilting of the cover unit (24), can be guided at least partially along a curved outer contour (22) of the fastening part (12).

2. Wiper arm according to claim 1, characterized in that a positive engagement can be produced between the rib (30, 32) and fastening part (12).

3. Wiper arm according to claim 2, characterized in that at least one nose (50) for hooking on the fastening part (12) is provided on the inner side of at least one side surface of the cover unit (24).

4. Wiper arm according to claim 3, characterized in that the fastening part (12) has a crosspiece (20) which corresponds to the nose (50) and can be engaged by the nose (50) in order to fasten the cover unit (24).

5. Wiper arm according to claim 1, characterized in that at least one nose (50) for hooking on the fastening part (12) is provided on the inner side of at least one side surface of the cover unit (24).

6. Wiper arm according to claim 5, characterized in that the fastening part (12) has a crosspiece (20) which corresponds to the nose (50) and can be engaged by the nose (50) in order to fasten the cover unit (24).

7. Cover unit (24) for at least partially covering a wiper arm (10) for a window wiper system, with a top side and two side wings (26, 28) which are open towards a front side (34) and are connected via a closed rear side (36), characterized in that an inwardly pointing rib (30, 32) elongated in a direction generally aligned with the top side is provided on at least one of the side wings (26, 28), which rib can be used, in a tilted state, to produce a latching connection to a fastening part (12), the rib (30, 32) being spaced from a rotary support (52, 54) of the cover unit (24) and where it is further located between the rotary support (52, 54) and the top side (40) and, upon tilting of the cover unit (24), being guided at least partially along a curved outer contour (22) of the fastening part (12).

8. Cover unit according to claim 7, characterized in that the inner side of the at least one side wing (26, 28) has a nose (50) for hooking on the fastening part (12).

9. Cover unit according to claim 8, characterized in that both side wings (26, 28) have a respective rib (30, 32).

10. Cover unit according to claim 9, characterized in that it is formed from a glass fiber reinforced plastic.

11. Cover unit according to claim 8, characterized in that it is formed from a glass fiber reinforced plastic.

12. Cover unit according to claim 7, characterized in that both side wings (26, 28) have a respective rib (30, 32).

13. Cover unit according to claim 12, characterized in that it is formed from a glass fiber reinforced plastic.
